WEATHER CONDITIONS

Season phenology:

Weather conditions:

The summer was colder than normal, with temperatures below +10øC. Snow retained until the second week of July in shadowed sites. Sea ice near shores disappeared in the first week of August. Eastern to north-eastern winds of moderate velocity predominated, and quite often turned into strong one. Calm weather was recorded only in late July. Precipitation was abundant, seemingly above the average.

BIOTIC CONDITIONS

Rodents abundance evaluation:

high

Breeding conditions:

Lemmings were numerous, while Arctic Foxes were strangely less common than in 1999. Wolves were common (fresh tracks observed constantly) that could have moved Arctic Foxes away. Two polar bears were present in the area, and a weasel was noted with brood. Six breeding pairs of Rough-legged Buzzards and one nest of Snowy Owl with 5 chicks were recorded at an area of 25-30 sq.km.
Recorded birds included abundant eiders, Long-tailed Ducks, various waders, White-fronted and Bean geese, Snow and Lapland buntings, Redpols, Pied Wagtails and Wheatears. A flock of 11-12 Snow Geese stayed near Svyatoi Nos Cape from 25 August to 5 September.
